Abstract

The development of Information and Communication Technology (ICT) affects the learning process. So, this study aims to produce a product of web-based teaching materials on radioactivity-oriented character education materials that are tested for quality and feasibility and can help teachers and students in learning radioactivity materials. The research used a design-based research model, which used a 3-D technique (i.e. Define, Design, and Develop) to develop teaching materials in this study. The instrument used consisted of a web feasibility judgment sheet in facilitating character education, content feasibility, visual design feasibility, and navigation feasibility used in a limited trial through two stages, namely the expert test stage and the user test. The expert test was conducted by three material and media experts. The user test was conducted by three teachers and 30 students of senior high school students (grade 12). The results of the limited trial overall show that web-based teaching materials are feasible in terms of facilitating character education, content, visual design, and navigation.

Abstract

Scientific literacy (LS) is the ability to engage with science-related issues, and with the ideas of science, as a reflective citizen. Thus, some developed countries provide policies, making that LS capabilities are provided to school curricula. However, some research reveals that this alleged ability has not been optimally provided in science learning, thus, students' LS abilities are still low. Pre-experimental research with a one-group pre-test-post-test design aims to get an overview of increasing LS capabilities in the competency domain through the application of a scientific approach. The study was conducted in one of the public schools in the city of Bandung using 30 samples taken randomly. The effectiveness of the increase was measured using the normalized gain value g on 20 essay questions with validity test results of 0.77, and reliability of 0.87. The results showed an increase in the K1 aspect (explaining scientific phenomena) g= 0.75 (high category), an increase in the K2 aspect (evaluating and designing scientific research) g= 0.46 (medium category), while an increase in the K3 aspect (interpreting data and evidence) g= 0.15 (low category). This shows the need for a mentorship process to build epistemic knowledge in analyzing and inferring experimental data in a scientific approach.
